JOHN CALVIN STUART, OF DALARK, ARKANSAS.

CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 483,640, dated October 4, 1892.

Application filed m 24, 1892.

To all whom it may concern:

Be it known that I, JOHN CALVIN STUART, a citizen'of the United States, residing at Dalark,in the county of Dallas and State of Arkansas, have invented certain new and useful Improvements in Railroad-Couplers; and I do declare the following to be a full clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

My invention has relation to car-couplers; and it consists in the novel construction and arrangement of its parts hereinafter set out in this specification and the claims hereto attached.

The object of my invention is to produce an automatic car-coupler that can be operated from either side or from the top of the car without the operator being compelled to go between the coaches either to couple or uncouple the same.

In the accompanying drawings, Figure 1 is a side elevation of my coupler. Fig. 2 is an end elevation, and Fig. 3 is a longitudinal sectional view of the coupler.

My invention is described as follows: a is the draw-head, on the upper face of which is attached a frame 11. The draw-head is provided with a pin-seat c, which works back and forth in the throat of said draw-head. Said pin-seat is provided with a neck 0, which passes through the perforation in plate 0 while a nut is screwed on the rear end of said neck in groove c and works against the rear face of said plate. A spiral spring 0 works around said neck 0, one end abutting against the shoulders of said pin-seat and the other against the front face of said plate 0 The object of the nut c is to prevent the said pinseat from jumping too far forward, and any other device for securing the neck in place that will answer the same purpose may be used, one of the main objects being to use something that will not come oif. A shaft 61 passes through said draw-head just in rear of its mouth and above its throat, to which is rigidly secured a coupling-link c, and to each end of said shaft is secured a crank-handle d. The handles of these cranks are heavy Serial No. 434,160. (No model.)

and are set on said shaft in such relation to the said coupling-link that when they are hanging down the said link will stand up. Their combined weight is considerably more than that of the link, so that the link will automatically be raised by the weight of said handles and be out of the way of the link of the approaching draw-head. One end of said link is solid and has through it a square perforation, which fits on a square part of said shaft (1. Said link is solid for about one half its length, the other half having a slot in it to receive the coupling-pin. When said link is in a position to couple, said solid part hangs down at a slight angle from said shaft d, and is bent so that the slotted part points horizontally forward to enter the approaching draw-head.

The lower end of the coupling-pin f rests on the pin-seat, and when the approaching link enters the mouth of the draw-head it pushes said seat back from under said pin, and said pin, from its own weight and the weight of its attachments, drops through the link and the cars are coupled. The upper end of said coupling-pin is bolted to a rod g, which has on its upper end a neck g, which passes through a perforation in the frame I), and on account of the shoulders g on said rod abutting against the under face of the upper part of the frame I) the coupling-pin can never entirely come out of the pin-hole in the drawhead. The upper part of said neck 9' is provided with a hook or ring, so that a cord or chain may be attached thereto and extend to the top of the coach, or the neck itself may extend so far. Said rod 9 is raised by slotted levers h, the ends of which extend nearly to the sides of the car, so that they may be reached without the operator going between the coaches.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination of the draw-head a, pinseat 0, provided with means for operating the same, shaft d, passing through said draw-head and having on each end weighted crank-handles d, link 6, having one end secured on said shaft, frame 12, secured on the upper face of said draw-head, rod g, having the shoulders g and neck said neck passing through a perforation in the upper'part of said frame, couprear face of said plate, link .2, hinged in the ling-pin f, bolted to the lower end of said rod front end of the draw-head, and coupling-pin g, and slotted levers h, fulcrumed to said f, providedwith meansforoperating the same,

frame and pivoted through its slots to said substantially as shown and described, and for I 5 5 rod 9, substantially as shown and described, the purposes set forth.

and for the purposes set forth. In testimony whereof Iaffix mysignature in 2.
